Perinereis linea is a widespread marine polychaete, has its complete mitochondrial genome reported here from Dongying, China. The 15,854 bp genome comprises 13 PCGs, 2 rRNAs, 22 tRNAs, and a control region, with typical annelid gene order and 64.63% AT bias. Phylogenetic analyses of 20 annelids places P. linea close to Perinereis aibuhitensis, clarifying nereidid evolution. This genome aids species identification and evolutionary studies.
